LAMP uxtrinenisiinn.

Application filed July 8, 1926. Serial No. 121,204.

This'invention relates to improvements in lamp extinguishers, a-nd'it consists of the construct-ions, combinations and arrangements hercindescribed'and claimed.

An object of the invention is to provide a simple and inexpensive yet thoroughly etficient device for manually extinguishing the flame of kerosene and similar lamps. the de vice also being capable of automatic operation in some instances, when for example,

the lamp accidentally falls. 7

Other objects and advantages will appear in the following specification. reference being had to the accompanying drawing, in

which Figure 1 is aperspective view of a lamp burner with the improved extinguishing device applied, 3

- Figure 2 is a detail cross section taken 4 substantially on theline 2-2 of Figure 1.

The burner shown in the drawing is of the typefamiliarly known as being used in connection with kerosene lampsalthough it may conceivably be another type of burner.

The burner compi'isesthe base 1. the dome which issuitably hinged at 3 upon the base to permit swinging back. and the wick tube 1 in respect to which the extinguishing device operates.

This device'is composed of ashutter plate 5 and a weighted shutter 6. The weight 7 of the latter shutter may be composed of lead or other suitable substance, the mode or application of the weighting substance to the 35 shutter 6 being such that there is formed a reces 8 which fits over and contains the exposed end of the wick whenthe shutters are in the extinguishing position (Fig. To this end the shutter 6 haswalls 9(Fig. 4o 1) which not only completes the recess mentioned but also provides places at which the actuating lever 15 extends for the purpose of swinging the shutter 6 upon its pivots or bearingsin order to lift it to the extinguishing position.

Branching fingers 16 of the lever 15 provide the support for the lever; To this end the exitteinitiee the branching fingers are bentoutwardly at 17 and introduced in holes 18 formed in a conveniently raised part of the base .1. The lever15 terminates in a flat button 19, which the operator may depress to actuate the extinguishing device.

A pair of supporting arms 20 carry the shutter plate 5. These are pivoted upon the base as at 21. The ends of the arms 20 are 'bent over in curved format-ion against one side of the plate 5 (Fig. 1) where they are gripped at two places by portions of the closing position also swinging the shutter 5'upward upon its pivot into position to meet the shutter 6 and form a closure over the wick W. The plate 5, in meeting the edge ofthe'shutter 6. completes the foregogoing recess, forming a chamber around the.

Wick and extinguishing the flame.

The operation is readily understood. The shutters 5 and 6 normally assume the separated or'open position in Figure l. The shutters 5a'nd 6 and the actuating lever 15 are independent of each other each being movable upon its own pivot. But the weight of the shutter 6 has a. controlling effect upon each of the elements.

In gravitating to the foregoing open or separated position the shutter 6 necessarily carries the tongue 13 downward until the latter rests upon the base 1. The weight 7 is sufliciently'heavy to overcome the lever 15, the tongue 13 therefore bearing down upon the finger lt and holding the lever 15 with its button 19 in the elevated position. The shutter 5. in turn, rests upon the tongue 13 and thus gravitates to the open position also. If the operator were to lift the weight 7 independently of the lever 15. the weight of the free end of .the lever would predominate over the weight of the shutter 5. and thus move the latter to the closed position. However, this is not done in practice and the weight 7 therefore insures holding both shutters open and the lever 15 in the elevated position.

Should it be desired to extinguish the its pivot 21. ioth shutters are thus carried upwardly (Fig. 2)) until they assume a closed position over the wick W. The recess 8 in the shutter (3, together with the shutter plate terms a chamber in which the flame is snutled out.

The foregoing description may be suppleu'iented by a statement of the adt 'antag 'es of the invention. Although kerosene lamps have been widely displaced by more modern means of illumination, it is nevertheless the fa *t that they are still. used to a large ex tent. principally in rural communities. Churches. meeting houses and residences are the frequent scenes of use of kerosene lamps. These are often held in brackets on the wall, and inasmuch as thev are quite out of reach for the oxtingluishino of the flame by the more or less common method of blowing down into the chimney. it becomes convenient to provide the lever 15 which the operator may use by simply reaching up. It is deemed an obvious expedient to attach a chain to the lever 15 so that the lamp may be reached in case it is mounted exceptionally high.

While the construction and arrangement of the improved lamp extinguisher is that of a generally preferred torm, obviously, modifications and changes may be made without departing from the spirit of the invention or the scope of the claims.

1. A lamp extinguisher comprising a base and a wick tube, a pair of shutters, means by which they are pivotally mounted upon the base beside the wick tube, actuating means mounted upon the base operatively engaged with one of the shutters to move it upon its pivot. and means on the other shut- (or engaged with a part oi. the first shutter so that both shutters move upon their pivots simultaneously to the closing position over the wick tube.

2. A lamp extinguisher comprising a. base and a wick tube. a pair oi shutters, means by which the shutters are pivotallv mounted upon the base at opposite sides of the wick tube, a tongue incorporated in one of the shutters. a lip incmporated in the other hearing on the tongue, and actuating means pivoted upon the base having); a finger engaging; the tongue for simultaneously moving boti shutters to the closing position upon operation of the actuating means.

3. A lamp extinguisher eon'iprising a base and a wick tube, a pair of shutters, supporting arms for each of the shutters, means upon the base by which portions of the arms are pivotally mounted. a tongue incorporated in the pivotal mounting of the supporting arms oi one oi the sl'lutters, a lip carried by the other shutter being in engagement with the tongue. and an actuating lever pivotally mounted upon the base having a finger en- .oganinp the tongue for lifting the tongue and lip simultanemusly to move the shutters to a closing; position over the wick tube.

4-. A, lamp extinguisher comprising a base and a wick tube, an actuating lever pivoted upon the base having a finger at one end and a button at the other, a shutter plate pivotallv mounted upon the base and having: a lip situated over the linger, and a weighted shutter pivotally mounted upon the base having a tongue disposed between the finger and lip, said weighted shutter depressing the finger by means of the tongue to keep the button in elevated position, said lip gravitating to a resting position upon said tongue.

In combination with the base and wick tube of a burner, a pair of supporting arms pivotally mounted upon the base extending to sides of the wick tube opposite to the pivots thereof, shutters affixed to the ends of the pairs of supporting arms, one of the shutters being weighted. the other consisting of a plate having bent over portions grippins! the ends of the respective supporting arms, a lip on the latter shutter, a tongue formed on the supporting arms of the former shutter, an actuating; lever having branching lingers pivotally mounted upon the base, and a finger m'tendine beyond said branching fingers into engagement with the tongues anthe purposes described.
